he should have figure out what you're asking though

CALLED THEM TODAY SENDING IT OUT THANKS FOR FINDING THAT SITE SHARP.

don't want to discourage you but i doubt this will solve the issue (i hope it will, worth a shot but slim chance imo, it's cheap so no real harm if it doesn't help you're just back at square zero).

got the dampener today gonna try it tomorrow. wish me luck. gonna take a close look at the butterfly. do you have any suggestions. i know i kept telling you it seems to be working as it should but if i wire it back the whole way back what does that do. i thought it worked somewhat like a dump valve but thats not right is it. and yeah i dont think it (dampener) will fix it wither but its a cheap try. they sent me an email stating that they have sold thousands for all years of jeeps and have never had one that it was not compatible with. you know i remember when this thing would go into boost and make power i would get a very strong smell of raw fuel. that being said would a problem with the butterfly allowing an excape of boosted intake air/fuel be a possibility?  the smell seems to come from the front of the vehicle not the exhaust. not positive but im pretty sure. i think that if this is not an electrical issue that seems to be the only part of the sysem that could cause that smell. i checked thoroughly for anything that could cause a vacuum leak and dont see anything. this is my last best shot before i nix the whole thing. if anything new comes in that jeep brain of yours let me know.

I'd like to see some closeup pictures of all things we discussed before i make any further assumptions. I agree with Split Second as far as it should work and more to that that you shouldn't get the 1 spot problem. the reason i asked that you have the bypass butterfly blocked open (and without the belt also) is so you can test the intake just like you'd run stock without the supercharger and stock manifold (with stock injectors and no ftc or enricher). If you can't get it to work like that (it will not produce any boost especially without the belt) you won't make it work with the ftc and boost. Like i said, it can be something with the way it's all connected (vacuum, bypass valve, etc) or something with that intake (you mentioned the injectors are not angled towards the intake valves so that can be one problem). Other than that i got nothing.

called floscan today to  ask if it made a difference if i installed the pulsation dampener on the front or rear of the fuel rail and he said it doesnt matter cause it isnt gonna work anyway. not made for what i wanted it to do. this after another person there last week said sure it will work, ordered gasket today try it out tomarrow. i did lock the butterfly back with belt on before i took it apart with no affect. gonna try it tomarrow alll together then put belt on and see what happened

same as before. 2000 rpm goes dead lean and gives violent jerk then continues on. still has bad tip in lean spot which can be corrected by raising up the map in that area but along with the correction comes a very high idle on coast down. seems like fuel puddleing in the intake or something like that. it eventually comes back down but it can take as long as 30 seconds. no matter what you do with the mapping nothing affects the 2000 rpm lean spot. think im done now. this thing really needs to go to a yj owner who could use it with none of these issues.

it's got nothing to do with being a YJ or TJ

obd2 is what i was refering too. guess what i found. an avenger supercharger for a 2.5l tj on ebay last night. i messaged the seller and asked him if he had the 2000 rpm hiccup  when he had it on his and he said yes. he said he made it less noticable by maxing the values on the ftc map at that rpm starting around 0 vac.(the same thing i did) only it didnt work well for me and once the o2 was re attached and driven for a while it got worse. he pulled it off and installed a v8 and is selling it on ebay now. texted him and asked if he still had his map saved just to see but havent heard from him back yet.

obd2 is only the standardized communication with external scanners and self emissions diagnosis (second O2 sensor), otherwise the operation and inputs are the same. most of the sensors are identical or almost identical, you'll have different connectors but otherwise it's the same part. ECU is different (but same operating principles).

sharp got a question about adjustable idler by powersteering pump. i snapped off a bushing that holds idler on. looking for a n exploded view to see if i assembled it wrong after taking supercharger off. i have a thick spacer washer in back then pully then bushing then bolt. am i missing any pieces?
